It is a flat and rectangular piece to which the corners have been trimmed and made folds to present a symmetrical shape in "MH, configured by two forks

(1, 2) Y una zona central (3) en "UH. (1, 2) And a central zone (3) in "UH.

Las horquillas (1, 2) se componen de un semicírculo (4 ) de dimensiones relacionadas con el contorno de las varillas, prolongándose en sendos brazos, uno exterior (5) y otro interior (6), para formar una "UH
The forks (1, 2) are composed of a semicircle (4) of dimensions related to the contour of the rods, extending in two arms, one outer (5) and another inner (6), to form a "UH

invertida. Los brazos (5, 6) de cada horquilla (1, 2) se cierran progresivamente respecto de la longitud del diámetro del semicírculo (4) hasta una distancia entre ellos que será menor que la sección de la varilla transversal de la bandeja portacables. inverted The arms (5, 6) of each fork (1, 2) are progressively closed with respect to the length of the diameter of the semicircle (4) up to a distance between them that will be less than the cross-sectional section of the cable tray.

Los brazos exteriores (5) de las horquillas (1, 2) finali zan en aletas (7) abiertas hacia el exterior del dispositivo en un ángulo de entre 45° a 90°, preferentemente 60°, con respecto al plano de simetría. The outer arms (5) of the forks (1, 2) end in fins (7) open towards the outside of the device at an angle between 45 ° to 90 °, preferably 60 °, with respect to the plane of symmetry.

Este diseño permite que la pieza tenga elasticidad al poder abrirse ligeramente los brazos exteriores (5) de las horquillas (1, 2) cuando se presionan las aletas (7) sobre las varillas (8, 9). This design allows the piece to have elasticity by being able to slightly open the outer arms (5) of the forks (1, 2) when the fins (7) are pressed on the rods (8, 9).

Para efectuar el acoplamiento de dos tramos (1, 11) de bandej as portacables, se posicionan las aletas (7) en las varillas transversales (8, 9) situadas en los extremos de los tramos de bandeja (1, 11) a unir. La inclinación de las aletas (7) servirá de guía para el rápido encajamiento de la pieza entre las dos varillas (8, 9). A su vez, esta inclinación provocará que ante la presión manual que se efectúe para instalar este dispositivo de unión, los brazos exteriores (5) de las horquillas (1, 2) se abran lo suficiente para superar el contorno de las varillas (8, 9) Y que éstas se encajen en las horquillas (1, 2), quedando la parte central (3) del dispositivo de unión entre los dos tramos de bandeja (1, 11) unidos. To make the coupling of two sections (1, 11) of cable trays, the fins (7) are positioned on the transverse rods (8, 9) located at the ends of the tray sections (1, 11) to be joined. The inclination of the fins (7) will guide the rapid engagement of the piece between the two rods (8, 9). In turn, this inclination will cause the external arms (5) of the forks (1, 2) to open sufficiently to overcome the contour of the rods (8, before the manual pressure is applied to install this joining device). 9) And that these fit into the forks (1, 2), leaving the central part (3) of the joining device between the two tray sections (1, 11) connected.

Se instalará, preferentemente, un dispositivo de unión en las paredes de la bandeja. En la base se colocarán uno o varios, dependiendo de la anchura de la bandeja portacables. Preferably, a joining device will be installed on the walls of the tray. One or more will be placed on the base, depending on the width of the cable tray.

Los dispositivos de unión se colocan desde el interior de la bandeja, para quedar situadas las aletas The joining devices are placed from inside the tray, so that the fins are located

(7) en la zona exterior una vez encajados en las varillas,
